When playing a game of magic with Buster, Darby casts a magic spell to turn in into a frog. She is surprised when a real frog shows up, wearing a friendship bracelet for Christopher Robin. Worried that she has turned her friend into a frog, she calls the Super Sleuths into action. They try their best to think of ways to turn Christopher Robin back into a human, or barring that, at least keep him happy.
